ok I need some expert wheel advice... I do not know how it all plays into one another .... I will be running a 4" lift with 37" mud grapplers they are rated at being 13.5 inches wide ... The wheels I am looking at or would like to run is from American Racing called "Chamber " with teflon coating, series 3985... the wheel is 18" bolt pattern 5 on 5.5 and back spacing is 4.5 offset at 19mm.... I know I will have to run an adapter to get that bolt pattern but how far will that push me out past the fenders in inches... do you think I will rub anywhere or do you think I will be fine... what do you think of this set up?.. and what adapters are the best to run?... thank you for your help...

 

this is what it looks like thanks again for your help

 

That's a really good looking wheel, but with the backspacing being 4.5", + the 1.5" spacers/adapters, that would leave you with the equivalent of 2" backspacing. Those are going to stick out quite a bit. I would personally try to find some wheels with the correct bolt pattern and back spacing to start off with. Good luck.

 

I found them with the correct bolt pattern but they still have 4.5 back spacing... so should I still use a spacer to run the 37 x 13.50...

 

How wide are they? I am guessing 9". I think you should be fine, but you may want to wait for someone who is actually running that setup to chime in.
